if, sed or awk with conditions

I do not know how to do this unless I use a bunch of if statements. I need a script to replace numbers in each record in a file. I am really getting tangled in this web.
If a fieldA (19 positions) is greater than 14 digits, I have to change the data (resulting fieldA is fixed 19 postions).
If there are preceding zeros. For example:
'000123456789012 ' would be changed to '123456789012 '
'001234567890123 ' would be changed to 1234567890123 '
'012345678901234 ' would be changed to 12345678901234 '
'123456789012345 ' would not be changed but would report error

I would appreciate any help or direction. Thanks.

filectime - Gets inode change time of file

SYNOPSIS
int filectime (string $filename) DESCRIPTION
Gets the inode change time of a file. PARAMETERS
o $filename - Path to the file. RETURN VALUES
Returns the time the file was last changed, or FALSE on failure. The time is returned as a Unix timestamp. EXAMPLES
Example #1 A filectime(3) example <?php // outputs e.g. somefile.txt was last changed: December 29 2002 22:16:23. $filename = 'somefile.txt'; if (file_exists($filename)) { echo "$filename was last changed: " . date("F d Y H:i:s.", filectime($filename)); } ?> ERRORS
/EXCEPTIONS Upon failure, an E_WARNING is emitted. NOTES
Note Note: In most Unix filesystems, a file is considered changed when its inode data is changed; that is, when the permissions, owner, group, or other metadata from the inode is updated. See also filemtime(3) (which is what you want to use when you want to create "Last Modified" footers on web pages) and fileatime(3). Note Note also that in some Unix texts the ctime of a file is referred to as being the creation time of the file. This is wrong. There is no creation time for Unix files in most Unix filesystems. Note Note that time resolution may differ from one file system to another. Note The results of this function are cached. See clearstatcache(3) for more details. Tip As of PHP 5.0.0, this function can also be used with some URL wrappers. Refer to "Supported Protocols and Wrappers" to determine which wrappers support stat(3) family of functionality. SEE ALSO
